I think you mean his paper "This is the Best Paper Ever on In-Memory Multi-Version Concurrency Control" which is available here: http://www.cs.cmu.edu/~pavlo/papers/p781-wu.pdf http://www.cs.cmu.edu/~pavlo/papers/p781-wu.pdf By the way, his courses are really excellent. I highly recommend subscribing to the CMU Database Group channel on YouTube.
